加福尔号上的这是部什么雷达？

RAN-40L (Italy), Naval/coastal surveillance and navigation radars

Type
L-band (1 to 2 GHz) long-range early warning radar (Italian military designation believed to be SPS-798).

RAN-40L早期预警雷达，义大利官方编号据信为SPS-798，L波段（1~2GHz）操作。

RAN-40L衍生自RAT-31DL陆基长程搜索雷达，都为Selex出品。

Description

Derived from Selex's experience with land-based 3-D long-range radars (particularly the RAT-31DL and its derivatives), the RAN-40L is equipped with a 'fully' solid-state, active, phased array antenna and is quoted as having maximum (against air targets) and minimum ranges of 400 km and 180 m respectively.

全固态电子组件，有源相控，最大搜索距离400千米，最小搜索距离180米

The sensor's instrumented range envelope is divided into 'intervals' in which differing waveforms are used. Here, a short-range (SR) waveform is used for sea, land and weather clutter suppression, with a long-range (LR) format providing optimised overall coverage and electronic counter-countermeasures proofing.

雷达收发工作交替使用两种封包（envelope），第一是Short Range，扫瞄海面丶沿岸与大气（应该是提高解析度丶牺牲距离）。第二是Long Range，全空域搜索，高电子对抗性能。

RAN-40L obtains radar coverage by means of phase scanning in elevation and mechanical rotation in azimuth. In more detail, the radar deliverers 360° coverage in azimuth, with its antenna rotating at 6 or 12 rpm.

垂直向为相控扫瞄，水平方位360度机械旋转。水平回旋速率6RPM或12RPM。

RAN-40L makes use of two independent and simultaneous pencil beams for both transmission and reception. 'High' elevation accuracy is maintained through the use of the monopulse technique and the radar's receiver channel is of a 'wide-range' linear format with a 'high' dynamic value.

同时使用两道独立的高精确度笔状波束，分别是传输和接收，单脉冲（monopulse）技术精确判断高度。接收频道为广区线性格式，高动态值（？）

Digital pulse compression techniques are used to produce an average/'low' peak power regime that is optimised to provide resistance to attack by anti-radiation missiles without any reduction in resolution.

应用後端脉冲压缩使峰值功率降低，平均的功率输出可避免遭敌方截收，但不影响解析度。

The sensitivity time control laws employed avoid saturation in high reflectivity conditions, a capability that when combined with frequency agility, allows the radar to operate in 'intense' clutter and countermeasures polluted environments.

一种控制律（sensitivity time control laws）可防止雷达在复杂电磁干扰环境下饱和。

Other electronic counter-countermeasures provision includes low sidelobe values, sidelobe blanking, a 'large number' of operating frequencies, frequency analysis on azimuth sector, automatic

其他电子对抗措施：低旁瓣丶旁瓣遮蔽丶大量操作频段可选丶方位角频率分析等。

对空对海警戒雷达？

RAN-40L三座标远程警戒雷达，D波段，作用距离250海里，

RAN-40L三座标远程警戒雷达，D波段，作用距离250海里，

和地平线、45、F124、省级用的那个叫什么L雷达什么关系？是叫Smart-L吧。

值得关注 发表于 2010-11-27 08:01

没有关系，是Selex先前RAT-31DL陆地警戒雷达的舰上版。

没有必然关系分属两个不同公司

地平线、45、F124、七省级上面的SMART-L是荷兰信号公司研制的
荷兰信号公司现在属于THALES财团

多谢各位高手指教，受益匪浅。

二楼给解释的够详细，有看头。

另外加福尔号上的32垂发配什么导弹啊？网上搜索一个页面也找不到，据说席尔瓦现在只能上紫苑，难道16 aster 30  16 aster 15？航母还配远程防空弹？要是32aster15是不是显得有点儿多余呀。

哎呀，估计我楼上说两句答谢的话，又觉得教我点儿东西是被我占了便宜了，都不吭声了。其实教别人点儿现成儿的东西我也没少干呢，只不过不是在CD，因为在小白聚集地我算是知识丰富的，在CD我就是小白。

为了有人回复，送两张图吧。

远程三坐标吧
